It took scientists such as Louis Pasteur to take yeast from the metaphysical realm into something that we can now understand and manipulate. There are two basic styles of brewer’s yeast: ale and lager. Ale yeast (Saccharomyces cerevisiae – “sugar fungus ale”) works at warm temperatures (15-25C) in the brewery and forms a vast blanket of froth on top of …

Diseases occur in our midst because of many factors and reasons. According to scientific researches and early pioneering efforts conducted on such diseases as cholera and gastro-enteritis by a German, Robert Koch, and the Frenchman, Louis Pasteur, on the microbes, these diseases occur in our midst when the water and food items we consume are contaminated, just as TB, measles, …

Single-celled yeast organisms were first used in baking and fermentation 4,000 years ago in ancient Egypt. Centuries later, famed French microbiologist Louis Pasteur discovered that alcohol was the natural by-product of yeast fermentation. Read the full article…

 by Louis Pasteur (with the Collaboration of Mr. Chamberland and Mr. Roux) Originially published in the Comptes Rendus de l’Academie des Science 92:1378-1383, June 13, 1881. In a lecture which I presented to the Academy last February 28, the purpose of which was to discover a method for preparation of attenuated anthrax, I spoke on behalf of myself and my …

His father was quite strict which was common for a school principal, but his expectations must have been appropriate for this precocious boy. His father died suddenly when Émile was eight years old. His mother’s …

GOLD MEDAL, HEALTH EXHIBITION, 1884 The Chamberland and Pasteur Filter is the joint production of the celebrated Professor Pasteur and his co-worker Dr. Chamberland, originally for the express purpose of eliminating disease germs and absolutely purifying waters used by them in Dr. Pasteur’s experiments. The method of filtration is through specially prepared porcelain tubes used chiefly under pressure. No impurities …

This article is an excerpt of Gibson’s larger work, “The Wonders of Scientific Discovery.” It has been remarked in the preceding chapter that in the mind of the general public it is in connection with hydrophobia that the name of Pasteur is best known. The year before Pasteur’s discovery there were sixty-seven deaths from hydrophobia in Great Britain alone. In …

A SHORT DESCRIPTION OF HYDROPHOBIA FROM THE EARLIEST TIMES DOWN TO THE END OF 1880 Seven years ago, in 1880, rabies or hydrophobia had already been known, dreaded, and studied, in Europe, for more than 2,000 years. Countless authors had written upon it, beginning, so far we can ascertain, with Democritus in the fifth century B.C., down to and including …

“In 1876, Louis Pasteur brought beer forward by describing the basis for fermentation that beer was fermented not by chemicals but by microorganisms–that is, yeast. He noted that bacteria, mold, and wild yeast were often responsible for the sour beer that plagued France and other countries. With this new understanding, he and other scientists began to refine techniques that could …
